The Wellhead and Source Water Protection Plan (the Plan) for the City of Mounds View addresses the 6 municipal water supply wells used by the City: Well 1, Well 2, Well 3, Well 4, Well 5; and Well 6. Wells 1 and 4 pump water from the Tunnel City Group (formally referred to as the Franconia aquifer), Wonewoc Sandstone (formally referred to as the Ironton -Galesville aquifer), and Mount Simon Sandstone aquifer. Well 2 pumps from the Mount Simon -Hinckley aquifer. Well 3 pumps from the Jordan Sandstone aquifer. Well 5 pumps from the Prairie du Chien Group and Jordan Sandstone aquifers. Well 6 pumps from the Jordan Sandstone, Tunnel City Group, Wonewoc Sandstone, and Mount Simon -Hinckley Sandstones aquifers. Wells 1, 2, 3, 5, and 6 are primary water supply wells. Well 4 is classified as "out long term". The Plan was prepared in accordance the applicable portions of the State of Minnesota Wellhead Protection Rules (Minnesota Rules 4720.5100 through 4720.5590). In Part 1 of the Plan, wellhead protection areas (WHPAs) for the Mounds View wells were delineated as was the associated drinking water supply management area (DWSMA). The vulnerability of the Mounds View wells and the associated DWSMA to contamination was assessed. In accordance with Minnesota Rules 4720.5550, Mounds View Wells..l; 2, and 3 were classified as not vulnerable to releases of contaminants at the surface while Wells ,4, 5, and 6 were classified as vulnerable to releases of contaminants at the surface. The uppermost source water aquifer in over 60% of the DWSMA was classified as having low vulnerability to releases of contaminants at the surface. In the remaining approximately 40%,of the DWSMA, the uppermost source water aquifer was classified as being moderately,vulnerable to releases of contaminants at the surface. The Mounds View DWSMA extends into the cities of Arden Hills, Blaine, Lexington, New Brighton, and Shoreview. Part 1 of the Plan was approved by the Minnesota Department of Health on February 1, 2012. This document comprises Part 2 of the Plan and includes the following information: • A review of data elements identified by the Minnesota Department of Health as applicable to the DWSMA. • Results of an inventory of potential contaminant sources within the DWSMA. • Review of changes, issues, problems, and opportunities related to the public water supply and the identified potential contaminant sources. • A discussion of potential contaminant source management strategies and the goals, objectives, and action plans associated with these management strategies. • A review of the Wellhead and Source Water Protection evaluation program and Mounds View's alternative water supply contingency strategy.
